Erection

Injecting prostaglandin, a hormone-like stimulator produced in the body, induces erection. A note of caution: Although there are many Tribulus extracts available over the counter today, almost all of these have been found not to contain any significant amount of the active ingredient. The current diagnostic and statistical manual of mental diseases (DSM-IV) has included a listing for impotence. The practice, which involved inspection of the complainants by court experts, was declared obscene in 1677. Ultrasound is then used to see vascular dilation and measure penile blood pressure.

Duplex ultrasound is used to evaluate blood flow, venous leak, signs of atherosclerosis, and scarring or calcification of erectile tissue. One of the most promising herbs is the purified extract of Tribulus terrestris.

The current diagnostic and statistical manual of mental diseases (DSM-IV) has included a listing for impotence. To determine this, a man can simply wet and affix a small stamp on his flaccid penis before going to bed. To date, its effects on treating impotence and other sexual dysfunctions have been extensively studied. In these cases, all the plumbing is OK, but the otherwise healthy man is unable to achieve an erection. Tribulus had been used as traditional medicine to treat sexual dysfunction and male infertility in Europe and Asia for many decades before improvement in scientific extraction techniques allowed identification of its active ingredient, protodioscin. This device works quite well, although some men complain about the discomfort of the elastic ring in addition to the hassle of, well, pumping up. The former uses the peripheral nerves and the lower parts of the spinal cord, whereas the latter uses the limbic system of the brain. Other studies have suggested that Tribulus also acts by increasing the level of dehydroepiandrosterone (DHEA), a naturally occurring substance in the body believed to be important for a healthy sex drive. It is estimated that about 10% to 20% of impotence cases are the direct result of various psychological factors, such as low self-esteem, depression, and — especially — stress and anxiety (general and performance anxieties).
